Question

A pen is held 60cm from a cancave mirror of focal length 20cm. Describe the characteristics of it's image.

Answer 1

Answer:

The mirror formula is as follows :

1/u + 1/v = 1/f

u = image distance

v = object distance

f = focal length

Doing the substitution we have :

1/u + 1/60 = 1/20

1/u = 1/20 - 1/60

1/u = 1/30

u = 30 cm

Image distance = 30cm
